| Abstract: | TiO2 nanocrystalline codoped with Fe3+ has been synthesized by using sol-gel method. The re sults show that Fe3+ serves as charge-carrier traps and promotes holes interfacial transfer reaction,and nanocrystalline TiO2 co-doped with Fe3+ dopants enhances the photoreactivity significantly as compared with Fe3+ doped samples. |
